The RR Crossing Sound was included in my new LM-4S-G that I purchased last week. It was included in the new upgraded diesel sound that comes with the new module. Don Sweet said, this is the only way to get it at this time, plus the button was on my handheld when I fired up the engine for the first time. All being said, Don said it would have to be added only in a Rail Pro upgrade in the future, so if these sounds can be added some other way then I don't know about that, I will just wait for the Rail Pro upgrades to be available in the future. This is pretty much what I said in a previous post, so if you need more details, call Don.
